Well as far as I am aware, you do not need a catalyst, but you must be able to meet the emissions standards set with a catalyst, which are clearly near impossible to get on most cars without a catalyst. The 1992 law for catalysts within the EU may have been transposed and enacted in UK law based on emissions, but I do not know. More likely it was a manufacturer requirement and then backed up in operations by emission laws (i.e. Euro 3).
I think it does answer the question, if tested with your catalyst during a MOT and then removed, clearly the emissions will be higher and may breach the above regulation.
If tested without a catalyst and passes, then it probably won't breach the above regulation.
I don't think this is a well understood area.
